System.Collection.Generic.RandomizedStringEqualityComparer is not a GenericTypeDefinition."

Question

I am Getting "System.Collection.Generic.RandomizedStringEqualityComparer is not a GenericTypeDefinition.MakeGenericType may not be called on a type for which Type.IsGenericTypeDefinition is true." error while creating Visual C++ Win32 Console Application.

This is the ScreenShot of that error.

Rather than completely uninstalling, a better solution for this is to clear off the Component Model Cache in %USER_PATH%\AppData\Local\Microsoft\VisualStudio\11.0\ComponentModelCache.

After deleting the cache folder, just relaunch Visual Studio 2012 once again, and build your project.

Worked for me.
